Activists raided a laboratory in São Paulo, Brazil early Friday and took hundreds of dogs from the complex after claims that the lab was testing on animals. The protesters accuse Instituto Royal of mistreating animals for pharmaceutical purposes. 
The institute pushed back, denying mistreatment and saying that all tests conducted on animals fall within the legal requirements of the National Health Surveillance Agency (ANVISA). 
Brazilians took to the internet, giving the hashtag #InstitutoRoyal nearly 90,000 mentions.
